Abstract
An apparatus for clenaing and reclaiming the fume of Fe-alloy ore roaster is composed of horizontal afterheat boiler communicated to the flue of the said ore roaster, cooling-concentrating tank, washing tower, deposition pool under the tower, circulating pool at its side, liquid-colloid reactor, delivering pump and pipeline, and draught fan connected to the outlet. Its advantages are full use of fume afterheat, cleaned fume reaching the discharge standard, high recovery rate of SiO2 (98%) for preparing water glass, and low cost.
Description
The present invention relates to a kind of flue gas processing device of smelting equipment, particularly a kind of iron-alloy equipment for cleaning fume and preparing colloid.
The mineralising stove that is used for ferrosilicon production is the major equipment of iron alloy technology, and its flue expellant gas temperature contains a large amount of trickle SiO up to 400-500 ℃ in the flue gas
2Fine powder and SO
2Etc. objectionable impurities, as flue dust suitably not being handled, will cause very big harm to environment, in addition, waste heat does not reclaim and equals to waste energy.
The purpose of this invention is to provide a kind of recyclable waste heat and with SiO
2Fine powder changes into the iron-alloy equipment for cleaning fume and preparing colloid of useful materials.
Purpose of the present invention realizes by following scheme:
Iron-alloy equipment for cleaning fume and preparing colloid, the gas cleaning that is used for the hot stove in iron alloy ore deposit is reclaimed, its afterbody connects induced draft fan, its stem connects the hot stove flue in ore deposit, it comprises horizontal type waste heat boiler, cooling-concentrating tank, the washing tower that connects successively by flue, wash tower bottoms has settling tank, and there is circulating pool on its next door, also has liquid-colloid reactor and is used for pipeline and the pump that slurries are carried; Cooling-concentrating tank inside is the tubulation of walking flue gas, logical slurries beyond the tubulation; Washing tower is the spray-type sieve-tray tower; Reactor is the withstand voltage 10kg/cm of surpassing
2, have a reactor of whipping appts.
Invention effect of the present invention is embodied in: 1. through the be up to state standards atmospheric emission standard of regulation of the exhaust gas components of this device processes, fume afterheat is fully reclaimed, exhaust temperature≤40 ℃; 2.98% SiO
2Reclaimed and made industrial-grade sodium silicate; 3. facility investment is less, and the cost of improvement waste gas passes through SiO
2Utilization reduce significantly.
Fig. 1 is a structural representation of the present invention.
Below in conjunction with accompanying drawing the present invention is described in more detail.
As shown in Figure 1, the present invention is applicable to the gas cleaning recovery of the hot stove in iron alloy ore deposit, its front end is received hot stove flue 28 sides, ore deposit by flue 27, one turnover panel 26 is arranged on the interface, be used to control the flue gas trend, flue gas at first enters waste heat boiler 24, fire tube is arranged in the waste heat boiler, drum 19 is arranged above, there is chuck 15 in the exit, steam enters drum by upcast 16, introduce in the chuck of reactor 25 by pipeline 29 by drum then, for reactor provides thermal source, the flue gas that is come out by waste heat boiler enters cooling-concentrating tank 13 by flue 14, there is the tubulation of flue gas cooling-concentrating tank inside, logical liquid slurry beyond the tubulation, the liquid slurry is by pump 10 and respective line 17,18 carry turnover, the flue gas that is come out by cooling-concentrating tank enters from the bottom of washing tower 9, flue gas through washing is drawn by induced draft fan 4 by smoke pipe 2, and drain into atmosphere by sound damper 3 and chimney 1, washing tower has a settling tank 7 for 9 times, supernatant liquor of slurries is by pump 5 in it, pipe 8 is transported to the cat head spray, sieve plate is arranged in the tower, and the slurries in the settling tank are transferred P H value with alkali, make it keep alkaline state, the opening for feed place of pump in the pond is equipped with strainer 6,11, slurries are delivered to circulating pool 12 by pump 10 parts in the settling tank, and by pump 23 and manage 20 and send into reactor 25 and react, reactor 25 is the withstand voltage 10kg/cm of surpassing
2, and have the reactor of whipping appts 21, eduction pipe 22 is arranged on it.
